4 Claims.

The present invention relates to new and useful improvements in yarn carriers and relates more particularly to a yarn carrier wherein the thread is supported in spaced relation to the carrier on removable elements.

In the past whenever the portions of a yarn carrier over which a thread ran became worn by reason of the continuous movement of the thread over the carrier or were otherwise damaged, it was necessary to discard the entire yarn carrier and replace it with an entire new carrier which was both expensive and wasteful. The present invention is directed to providing a yarn carrier with thread supporting and guiding means of wear resistant material that hold the thread away from the surface of the carrier itself to prevent wear on the carrier and which are removably secured to the carrier so that they may be replaced upon becoming worn or otherwise damaged. The various objects and advantages of my invention will be apparent and best understood from the following description and the accompanying drawings in which:

Fig. 13 is a fragmentary View in perspective of another form of the invention; and

Fig. 14 is a section view taken along the line I l-l4 of Fig. 13.

Referring now to the drawings in detail there is a yarn carrier l of a type suitable for use in full fashioned hosiery machines. It will be understood, of course, that the present invention is not limited to a particular type of yarn carrier, but may be applied to various types of yarn carriers.

The carrier I may be provided with one or more thread guides, designated generally by the number 2 in Fig. l. The thread guide 2 directs a thread 3 in its movement over the carrier to a suitable thread-guide tube 4 that is held between spring-jaws at the end of the carrier. The thread guide 2, as illustrated in Figs. 1-3, includes a U-shaped member 5 that is secured in inverted position on the carrier l. The member 5 projects from the surface of the carrier I with the legs of the member 5 defining a passageway 6 through which the thread 3 may pass as it moves across the carrier to a delivery point and the passageway 6 will serve to direct the thread in its movement across the carrier.

The U-shaped member 5 has outwardly projecting shoulders that extend over and engage with portions of a circular thread-supporting member I. The thread-supporting member I is in the form of a ring made from a rod-shaped section of wear resisting material, such as a hardened steel wire that is resiliently deformable and is removably secured to the carrier by the member 5. The thread 3 in its movement across the carrier and through the member 5 rests on the thread-supporting member 1 and is held in spaced relation to the surface of the carrier. Thus, any wear due to the movement of the thread across the carrier takes place on the thread-supporting member I rather than on the surface of the carrier. The top of the member 5 may be sloped downwardly so that the threadsupporting member I may be forced downwardly over the top of the member 5 and is deformed sufficiently in this manner to permit portions of the thread-supporting member to be engaged beneath the shoulders of the member 5. The thread-supporting member I may be easily removed from the member 5 by deforming the ring with a pair of pliers to a shape that will permit the member I to pass over the shoulders of the member 5.

In addition to supporting the thread 3 and holding the thread away from the surface of the carrier I so as to prevent wear on the carrier, the ring I also reduces the area of the carrier contacting with the thread and consequently reduces the frictional drag on the thread 3 as it moves across the carrier. This makes it possible to guide the thread more easily and accurately and with reduced breakage.

In the form of the invention illustrated in Figs. 4 and 5, there is a U-shaped member 3 that is carried by the carrier 1 in an upright position. A circular, thread-supporting member 9 is removably held between the legs of the U- shaped member 8. The thread-supporting member 9 is also in the form of a ring made from a rod-shaped section of wear resisting material and the thread 3 runs through a central opening in the thread-supporting member 9. Thus, the thread-supporting member 9 directs the thread and holds the thread in spaced relation to the sur face of the carrier. legs of the U-shaped member 8 may be shaped to The opposed surfaces of the prevent lateral displacement of the thread-supporting member 9 when it is wedged between them. H

In the formof the thread guideillustrat'ed in Figs. 6 and '7, there is a U-shaped member 10 that has a passageway or opening 1 I through which the thread 3 passes. As the thread 3 passes through the passageway I I, it runs over a'thre'adsupporting member in the form of a wire clip lz made from a rod of wear resistant material. The ends of the wire clip 12 are fitted into openings in the sides of the member I to hold the wire clip in place on the carrier and the wire clip l2 may be readily removed or replaced by spreading the ends of the clip 12' and'moving it onto or off of thein'ezziber' ll. I

In the form of the'thread guide illustrated in Figs. 8 and'Q, there'isa U 'shapedme'mber ['3 that defines a passageway or opening I4 through which the thread 3 passes. A' thi-eadgsupportin member in the form'of a rod 25 of wear resistant material extends through the legit: thememher (3 and across the bottom of the passageway M defined by the legs of the member [3L The rod i5 is removably held in the legsefthe member [3 and may be removed'for replacement by sliding it out of the legs of the member [3;

In the embodiments of the invention illustrated in Figs. -14, theth'read tis supported'in its movement across the carrier by thread-supporting'members of wear resisting material that do not have passageways associated therewith. In the embodiment of the invention illustrated in Fig/l0, there isa thread-supporting member in the form of amber itfof wear'resisting material, such ashardened'steel, thatsupports" the thread 3"in spacedrelation to the surface of the carrier 1 in the'movernent of the thread'a'cross the carrier l. The roller 56 is supported on'the'carrier I by lips or flanges if? that extend in'an'angular relation to the carrier I. s, p v t In the embodimen'tof the invention illustrated in Figs. 11 and 12 a thread-supporting member in the form of a rotatable sleeve [80f wearresistant material supports thethrea'd'fi in'spaced rela tioirt'o' the surface of the carrier I. \The sleeve 13 is rotatably supported on thecarrieni by a wire clip ii; that is removably secured to' the carrier 1 by'a screw 253. V

In the embodiment illustrated'in Figs; 13 and 14, there is a thread-supporting"member in the form of a U-shaped wire clip 2| of resilient'we'ar resisting material that supports the thread S, in spaced relation to the surface of the carrier l. The ends of the wire clip 21 are fittedintospace'd openings the carrier I and re'silientlyfeng'a'ge with the carrier i to hold the clip removably in place on the carrier. The clip 2i maybe provided with a groove 22 at its center that serves to direct the thread 3 in its movement across the carrier and the carrier may also be provided with a corresponding groove 23 to accommodate the groove 22 of the clip 2|. I v

The members, such as the U-shaped members 5, 8, it, and 13, to which the replaceable threadsuppcrting members are removably secured may also be reinovably secured to the carrier, if desired, and in such case the threade-supporting member may be made a part of the U shaped member and removed with it. It will be noted, however, that in any case, the thread-supporting member is removable from portionsofthe thread guide 2 with the carrier and may be replaced without discarding the entire carriers'ince such members become worn from'the movement of the thread 3 across the carrier and require frequent replacement.

It will be apparent that those skilled in the art may make various changes and modifications in the embodiments of my invention as illustrated and described herein without departing from the scope of the claims as appended hereto.
